WILHELM KRAUSS, OF HALLE-ON-THE-SAALE, SAXONY, ASSIGNOR OF TWO FIFTHS TO WILHELM KUMPFMILLER, OF MUNICH, GERMANY.

CYLINDER RELIEF-VALVE.

SPECIFICATION forming part of Letters Patent No. 391,163, dated October 16.

(No model.)

To all whom it may concern.-

Be it known that I, \VILHELM KRAUSS, of Halle-on-the-Saale, Saxony,Germany, have invented a new Improvement in Cylinder Relief- 5 Valves,of which the following is aspecification.

This invention relates to an apparatus for evacuating the condensed water from the steam-cylinder; and it consists of the various features hereinafter fully described.

Figure I is a vertical section of the apparatus, and Fig. II shows a modification.

A is a cylindrical chamber,open at the bottom, with an inlet-nozzle, A,at its upper end, connected to the under side or lowest part of the steanrcylinder. In the inside of this chamber A an inverted cup, D, open at the bottom, is securely attached or cast on, leaving an annular space, R, between the outside of the cup D and the inside of the chamber A.

B is a plate to close the bottom of the chamber A, provided with a central outlet, E, to which the discharge-pipe E is connected. This plate or bottom B is bolted or screwed into the chamber A, as shown in Fig. I; or the same may be forced tight against the end of this chamber A by springs F, attached to lugs (2, arranged on the bottom B, and to lugs (2, arranged on the chamber A, as shown in Fig. II.

C is a ball smaller than the inside diameter of the cup D and capable of resting and closing the mouth of the discharge-hole E. The specific gravity of this ball must be less than the water displaced by the same.

3' The operation is as follows: During the exhaust of the steam the water stands in the apparatns on the chamber A some distance above the bottom of the cup D in the annular space R, while the inside of the cup D is filled with 40 steam. By the following admission of steam the same enters the chamber A through opening A, carrying the usual condensed water with it into said chamber, pressing upon the water in the space R and forcing the same 5 into the cup D. By this action the pressure against the lower half of the ball 0 will be increased, forcing thereby said ball O upward into the cup D, and thus compressing the steam in said cup until its pressure will be equal to the pressure of the steam acting upon the surface of the water in the space B. By the raising of the ball 0 the opening E of dis charge-pipe will be uncovered and the water in the cylinder A can escape through the same. When the water in the annular space R falls below the bottom edge of the cup D, steam will enter the cup D. The following expansion of the steam in the steam-cylinder will reduce its pressure, and consequently allow the steam in the cup D above the ball 0 to expand, forcing thereby the ball 0 and the remaining water in said cup downward until the ball 0 closes the Opening E and the water is forced down to be level again with the bottom edge of the cup D. The water which has not previously escaped through the opening will rise then in the annular space R and the operation be repeated.

WVith some engines, where through some cause or other an excess of condensed water will pass into and out of the steam-cylinder, and consequently into the apparatus,the plate or bottom 13 is secured and made tight against the bottom of the chamber by means of suitable springs, F, attached to lugs d, arranged on the chamber A,and to corresponding lugs, d, on the bottom plate, B, (see Fig. IL) whereby by any excess of water this bottom plate will be forced outward and the water allowed to escape, the bottom plate, B, being in that case provided with suitable guides, I).

What I claim is 1. In combination with a steamcylinder,the chamber A, with internal inverted cup, D, inlet branch A, bottom plate, B, with discharge branch E,and ball 0, arranged in the manner and for the purpose described.

2. In combination with a steam-cylinder,the chamber A, with internal inverted cup,D,ball O, and bottom plate, B, and springs F, as and for the purpose described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

\VILHELM KRAUSS.
